Compared to other fiber adapters in the marketplace, which support Wake on LAN (WOL) on either PCI 2.1 or PCI 2.2 systems but not both, these NICs support internal WOL feature through the PCI 2.2 bus, & have the capability to support PCI 2.1 WOL feature by using the external cable. The AT-2701FTX is resistant to signal degradation, snooping & interference, & is ideal for networks that require protection from electrical interference or where security is a concern. The small footprint, together with the low-profile option, makes this product a perfect choice for PCs equipped with small desktop solutions. Please note: server components such as memory & power supplies must match those already installed in a server. To avoid compatibility clashes or for advice, please contact us on solutions@ebuyer.com.
